Could someone tell me what 3-speed standard transmission was used on the 1959 F100 with a 223cid six? I am finding conflicting information. It is a column shifted side loader, four bolt mounting pattern, no inspection plate on top, and it is mated to a flat flywheel, NOT the "deep dish" variety. I do not believe it is the 2.77 transmission. Some casting numbers I found on the transmission: Top: 28 AF-7006-D Side: AB-722-B I really want to know if what I have is correct for the vehicle and not from another year. I also need a seal/bearing kit for it. Thanks all, -Kevin
Sounds like a typical mid 50s-early 60s Ford three speed. The side cover is rectangular shaped, lots of bolts holding it on, right? Order the seals/bearings for your truck as if it's the original trans, if they fit you know it might be the original trans. My guess is that it is. you could measure the center to center distance of the mainshaft and countershaft, see if it's 2.77"
<cough> Bump... It does indeed have a side cover. I am going to ***ume that this is a 2.77 transmission. It's pretty puny...about as big as a lunch box.
277's were top loaders....had a small 4 bolt tin cover on top. The shifter shafts came out the sides of the gearbox casting. These were pretty much strictly used on Falcons and early Fairlanes/Mustangs with the small six cyl motors. I believe these trannies came out in 1960. Very unlikely it was ever used on a truck. The 9 bolt side load/side shift trans was sometimes called the 2-15/16". Its origins go back to the mid 1950's. Some came with a traditional long tail housing and some had the very short tailshaft housing. This trans was synchronized from 2nd to high, but no synchro for first gear. This (almost certainly) is what you would have on your 1959 F100 pickup. There were different gear combinations depending on the engine size etc. It's a pretty common trans. We stock the bearings, gaskets, etc for them.
The numbers you have above ID the main case only. If one had the proper MPC of the period. one might be able to cross it in the parts index. There should be a metal tag, usually attached to the tail-shaft housing to main case bolt(s). As mentioned, the 2.77 is a very light 3/S. The 3.03 was the later T&C 3/S synchro first. Yours as mentioned should be then 2 15/16. These measurements are input shaft distance to counter-shaft.
Is this a "super rare" 2 15/16 (2.9375) option? This may be bad logic, but can I ***ume it is better/stronger than the 2.77 ? I dont think my puny 223 will put out enough juice to break it, but that is beside the point...
That's the most common Ford transmission of the '50's, right up to the mid-60's. They were behind FE's in wagons and trucks, I doubt your 223 will hurt it! BTW, your engine could very well be a 215.
Pretty certain it is not (I researched it when I bought the truck)...I HOPE it's not...I told the machine shop it was a 223. Is this what you are getting at?
Yes. The 2.77 was introduced in 1960 to be used in the FALCON/COMET series. While I am not 100% sure you have the 2 15/16, it is called a light-duty trans but the next step-up was a 3/S top loader or O/D. Yours will handle the six. One needs either the Specification Manual or the 1959 MPC to positively ID what you have.
My father and I are trying to find out what gears his 1958 F100 has, the casting numbers on this 3-speed are a bit different: 25 AF-706-D AB-7222-B the VIN plate says the trans code is A can you help?
